Support for iOS 9 will be removed.
All P-Edge media apps are compatible with Apple's newest operating system, iOS 12. You can keep using these apps without problems as soon as Apple releases the update.
Weerbericht Nederland, SevenBloks and Anikey have been tested and work as expected. iOS 12 will probably be released in september 2018.
During this year, support for iOS 9 will be removed. Users who want to keep using iOS 9 can still use older versions of these apps.
